This pin passes through the bolt carrier at an angle.įrom the top of the rifle you can see the other side of the charging handle’s retaining pin. You can see it in the center of the picture above. To remove the bolt assembly, the charging handle needs to be removed. This is located in front of the receiver and is simply unscrewed with an open end wrench. Since the gas port is hard to access, most rifles we take apart need this area cleaned. Once the roll pin is removed, the recoil system and spring can be removed. The gas block retains the action parts with a roll pin which needs to be drifted out with a roll pin punch. Removal of the fore end exposes the gas block. With the screw removed, the front end can slide off. After the rifle is safe and empty, I remove the screw located on the front of the forearm.

Unlike modern semi-automatic rifle designs, the Model 4, 742, and 7400 rifles are extremely difficult to take apart. We have a lot of older Remington semiautomatic rifles walk into the shop in need of repair. In this post we’ll take a quick look at the 7400 and how it is disassembled for maintenance. While I’m not particularly fond of either, they both offer shooters quick follow up shots and reduced recoil over traditional bolt action designs. Big game hunters in the United States traditionally had two options in semi-automatic rifles, the Browning BAR and Remington 7400.
